You need to use the Wacom Link adapter on the center USB-C port for the MSP hybrid mode - only that supports external signals into MSP. The Wacom Link needs a displayport signal for the display. If your computer does not provide displayport, an additional adapter converting the HDMI output of the computer to mini-displayport is needed. We did not test with PS4, and for other cases we see limitations in possible resolution and screen refreshrate.
